France's Eurovia aims to make roads change color to warn of ice

Heat-sensitive spoons designed for better cooking

Who among us has not been thwarted by the microwave at some point -- constantly having to heat and reheat, trying to get our food at that perfect temperature. While some take the smart appliance approach, those who enjoy a low-tech aesthetic might be interested in The Added Touch's color changing spoons. Each one is heat-sensitive and adjusts hue when your food reaches 120 degrees F, indicating that it is ready. While being the only color changing spoon we have seen that didn't come in a cereal box, it might also be the only one in our dish rack that doesn't melt or get to sparking when left in the ol' nuker.
